This test does nasty things with the root it runs in, in particular is kills and creates /dev/null which may result in /dev/null become 'deleted' for the tests running in paralles with this. The lattest is critical for uns flavor as ghost /dev/null will not be re-created (mknod fails). Signed-off-by: -

Instead of doing some dirs/files/links in launcher and some in libzdtm, make everything in the launcher. The library is then just to set up the namespaces. Signed-off-by: -

If we get EBUSY here, it means that we didn't umount in the test (i.e. we didn't call fini() on some path). We should just do that instead. Signed-off-by:

The kernel only requires that we supply a scope id to bind() when the source address is of certain types, so lets only save/supply the scope id in these cases. Signed-off-by:

This change does two things to be more defensive: 1. add a checkskip script which fails if __NR_seccomp isn't defined, and 2. allows seccomp_filter_tsync to compile even if it isn't defined (and then fails "gracefully" with a skip message if it does). The checkskip bits are necessary because zdtm.sh gets confused if the test exits 0 without actually invoking criu. Signed-off-by:

It's possiable, if a parent task lives in a sub-mntns and its child lives in the root mntns. A mount namespace is restored before forking children, so all children are created in parent's mount namespace. If a child lives in another mount namespace, we need to move it into the required mntns. Reported-by: Mr Jenkins Signed-off-by:

This tests c/r of the link-local scope-id argument to bind(). v2: sort the interfaces so diff works Signed-off-by:

Tycho Andersen authored
For some ipv6 scope types (link local, amongo others), we need to tell the kernel the ifindex of the interface whose address we want to bind to as well as the address itself. v2: use SO_BINDTODEVICE to get the ifname, and pass that through instead of using netlink to grab all the ipv6 sockets via rtnetlink.

nsid->mnt.ns_fd is initialized into 0, so currently fini_restore_mntns() closes the 0 descriptor if processes lives in a current mount namespace (NS_CRIU). Without this patch I get the following error: (00.166444) 4109: Inherit fd tty:[8800:d] -> 0 has been closed v2: typo fix v3: do nothing when processes are restored in the local mntns Signed-off-by:
